Analysis on Potential Sliding Surface of High Rock Slope

The basic theoretic problem of reasonable determination of rock failure surface or potential sliding surface need to be resolved as soon as possible in various rock architecture engineering. The paper studies potential sliding surface of high rock slope using comprehensive analysis method integrated with an engineering case. First,according to the results of tests in laboratory and evaluation of rock mechanical parameters, slope rock mass failure angles are calculated based on Mohr Coulomb criteria; Second,regularity of slope deformation and destruction is studied applying elastic plastic FEM numeric simulation method. According to the results of these two methods and based on the deformation and destruction model, potential sliding surface of high slope is determined, which is instructive for stabilizing calculation and evaluation of high slope in practical engineering.
